9477ea8735 Fix LargeObjectSpace::Contains to check if addr is in new space. 
Otherwise page header check is not quite robust: if there is a smi
at the same offset as Page::is_normal_page field, wrong result would
be returned.

That shouldn't be the problem for paged spaces as objects in those
pages do not span page boundaries and thus cannot mess with ::is_normal_page field.

41830911f3 Make following ES5 functions work with undetectable parameters/target (document.all): 
ObjectIsPrototypeOf
ObjectDefineGetter
ObjectLookupGetter
ObjectDefineSetter
ObjectLookupSetter
ObjectKeys
ObjectGetPrototypeOf
ObjectGetOwnPropertyDescriptor
ObjectGetOwnPropertyNames
ObjectDefineProperty
ObjectDefineProperties

I did not implement tests covering calls with undetectable parameters since I would need to make these tests native. Just thought it was not worth the effort. If you think tests would make sense, I can add them. We might want to allow other functions to receive undetectable parameters, but I am not seeing any good candidates.

51495beb78 Store type information with constants. 
Instead of testing the value of a constant frame element to determine
the type we compute its type information at construction time.

This speeds up querying the type information during code generation.

This change also adds support for Integer32 constants and sets 
the type information accordingly.

54f0a5b221 Expose debug context into the native code. This change is doing several things: 
1) Exposes Local<Context> v8::Debug::GetDebugContext().
Rationale: We can already get debugger context instance using various workarounds,
so exposing it explicitly in the API only makes things more clear.

2) Removes debugger.HasJavaScriptFrames() requirement for entering debugger context.
Rationale: Sometimes we'd like to call into debugger from the external native code.

3) Makes Debugger v8::Debug::Call execute on debugger context's global object.
Rationale: This is somewhat arguable, but temporary measure. We've agreed that we
should introduce a DebugAPI object that would expose necessary API in the debug-delay.
The problem is that it would take some time to define this API and it is not really
convenient to do that on the v8 land given the difference in v8 / host lifecycle.
The plan is to compose this API as a Debug.* wrapper outside v8 by means of exposing
debugger context's global object here, and once API settles down, upstream it to v8 and
start making Debug::Calls on this new DebugAPI object instead.
